So they're making $136 dollars per customer in profit. That doesn't seem unreasonable to me. 136 is much less than the crazy costs that people are complaining about.

Are people who like to quote these big numbers just not capable of critical thinking or is it just that they like the chance to rage at capitalism's supposed failings and they know their readers are too dumb to do division?

Perhaps you are referring to an appeals court ruling to that effect ("some deportees lacked criminal records and denied any meaningful judicial review or legal defense") ? This was overturned by the supreme court on the narrow grounds that the habeus petition should have been filed in TX, not judge shopping in DC.

The vast majority of these deportations are just shuffling people around the EU in what seems like a game of hot potato over who is supposed to be responsible for a given migrant. Deportations that actually get people out of the EU seem to be extremely rare afaict.

And you're really not sure this is less draconian than nazis?
